摘要 |
Provided is an asynchronous random access method in a packet-based cellular system, which includes the steps of: receiving a preamble from a mobile station; checking the received preamble to see whether the mobile station includes a mobile station identifier assigned by the base station; when the mobile station does not have a mobile station identifier, allocating first scheduling information to a control information block, allocating a first response message including a mobile station identifier assigned by the base station to a downlink shared channel, and transmitting the control information block and the downlink shared channel to the mobile station; and when the mobile station includes the mobile station identifier, allocating second scheduling information to the control information block, allocating a second response message without the mobile station identifier to the downlink shared channel, and transmitting the control information block and the downlink shared channel to the mobile station.
